Filtration apparatus

The LABSOLUTE® filter crucibles are made of borosilicate glass 3.3 and are therefore extremely resistant against high temperatures and chemicals. The crucibles are autoclavable and can be perfectly used for applications in qualitative analysis and preparative chemistry. The sintered glass filter disc has a porosity of 4 which equals a pore size of 5 -15 µm.

The LABSOLUTE® Buchner funnels are made of high-quality porcelain and comply with DIN 12905. They are glazed on the inside and outside and are characterized by an excellent resistance to lyes and acids with the exception of hydrofluoric acid.

The LABSOLUTE® Erlenmeyer shaped filter flasks with glass olive are made of high-quality borosilicate glass 3.3 and comply with ISO 6556 and DIN 12476. Together with the LABSOLUTE® Buchner funnels and suitable rubber gaskets, they form a perfect unit for almost all kinds of filtration applications in chemical laboratories. All LABSOLUTE® filter flasks are autoclavable and, because of their high wall thickness, also vacuum-proof.

We recommend a vacuum tube with an inner diamater of 8 mm to connect the filter flasks to a vacuum pump.

Due to the glass olive, the flasks do not comply with the requirements of the German product safety law (ProdSG).

Accessories Accessoires for LLG-Filtering apparatus

LLG-Microbiological Monitors and Analytical funnels provide a ready-to-use solution for the filtration of liquid samples using a manifold. No need for flaming or sterilization, reduces the testing time up to 70%. These 100ml units are suited for monitoring contaminants in all types of samples, from raw materials to finished products. In the case of Microbiological Monitors the nitrocellulose membrane is fixed to the unit. The filtration unit easily converts to a Petri dish, which can be labeled and incubated for further analysis. When using analytical funnels the nitrocellulose membrane can be removed and transferred to a Petri dish for further analysis. Adapter for use with a manifold is included.

For microbiological and analytical quality assurance in industry. 250 ml sterile plastic funnels reduce process time in colony and particle analysis. For use with Sartorius membrane filters and Sartorius cardboard culture plates.
Note: Biosart^®250 funnels can also be adapted to fit single filter holders or filtration manifolds.
